Our team for the “Hell Rabbit” project consists of three people: Frank Mason, Jorge Lara and myself. Frank is responsible for adding and modifying the code. Jorge will be searching for the additional components that can enhance our project. My … Continue reading →

For my final project, I will try to convert this ugly stuffed animal into an interactive toy the “Hell Rabbit”. This toy will be seating in a doorway and triggering people’s proximity with an IR sensor. When a person enters … Continue reading →

I decided to write about the ATmega328 microcontroller, since it is used in the most popular Arduino boards. This 8-bit processor is made by Atmel and belongs to the megaAVR series, which means that separate storage and signal pathways are … Continue reading →

Objective: take the player apart, document what is inside, then put the device back together, trying to vivisect it. Materials: MP3 MP4 Game Portable Multimedia Player, Precision screwdrivers, camera, flashlight, magnifying glass; Procedure: 1. Examine the device: It has a … Continue reading →

The TowerPro SG92R is a small and lightweight servo motor that can rotate approximately 180 degrees (90 in each direction). It has carbon fiber gears and control arms resulting in 2.5kg torque, with just 9g of weight. Because everything is … Continue reading →

Objective: dissect the POE Network Switch and its power supply, examine the inner parts, trying to understand how they work, then put everything back together; dissect small Chinese electronic device, examine inner parts, then put them back together, trying to … Continue reading →

The Sharp GP2Y0A21YK is a low cost ($13.95) infrared proximity sensor with an analog output that varies from 3.1V at 10cm to 0.4V at 80cm. It has a JST (Japanese Solderless Terminal) connector and needs either a pigtail jumper wire or … Continue reading →

After doing some more research on Arduino robotics, I found out that almost every robot is using some kind of a distance sensor. Probably I’m going to need one for my final project as well. I decided to look closer … Continue reading →

After searching the web for some cool Arduino projects, I found literally hundreds of great videos and tutorials. People are making all kinds of crazy stuff using Arduino: 3D printers, all kinds of robots, interactive musical artwork… even zombie scanners … Continue reading →
